Joint surfaces of the flanges 11 and 12 are sealed by an O ring 10. Further, bonding steps 13 are formed between the heater base 3 and the O ring 10 on the joint surfaces of the flanges 11 and 12, thereby preventing thermo-radiation from the heater base 3 from reaching the O ring 10 through the joint surfaces of the flanges 11 and 12.Type: GrantFiled: June 12, 2009Date of Patent: March 6, 2012Assignee: Canon Anelva CorporationInventors: Nobuyuki Masaki, Yuichi Sasuga, Masami Shibagaki, Hiroshi Doi

Patent number: 8124916Abstract: Apparatus and methods that minimize surface defect development in silicon wafers during thermal processing at relatively high temperatures at which silicon wafers are annealed and at less extreme temperature, or for other purposes. The apparatus and methods have utility to horizontally-disposed furnaces for silicon wafers and to vertically-oriented furnaces in which larger wafers can be thermally processed. A selectively-sealable process tube encloses silicon wafers during heating of the silicon wafers to a predetermined temperature, and a heating atmosphere supply system induces through the process tube a positive flow of a process gas, such as hydrogen or argon, that is non-reactive with solid silicon at the predetermined temperature. A process tube outlet vents gas from the process tube, and an impurity sensor in the process tube outlet detects oxygen and moisture in the vented gas to verify the purity of the atmosphere surrounding the wafers during thermal processing.Type: GrantFiled: April 16, 2007Date of Patent: February 28, 2012Assignee: Maxim Integrated Products, Inc.Inventors: Amit S. Kelkar, Larry Puechner, David E. Billings

Patent number: 8115140Abstract: A heater assembly configured to elevate a temperature of a processing element in a chemical treatment system is described. The heater assembly may be configured to uniformly heat a large area processing element, such as a processing element that spans a plurality of substrates. Additionally, for example, the heater assembly may be configured to elevate a temperature of an upper assembly, a gas injection assembly, a substrate holder, a chamber wall, or any combination of two or more thereof.Type: GrantFiled: July 31, 2008Date of Patent: February 14, 2012Assignee: Tokyo Electron LimitedInventors: Charles R. Launsby, Jay R. Wallace

Patent number: 8101889Abstract: In a built-in drawer type cooking device, an open/close door 2a and a heating container 2b that constitute a drawer body 2 are separably connected to each other. The open/close door 2a and the heating container 2b are connected via an insulator 10 to prevent a discharge phenomenon due to emission of microwaves. The open/close door 2a and the heating container 2b can be separated from each other with the drawer body 2 being drawn out, and thus the heating container 2b can be taken out of the cooking device and cleaned or wholly washed. An inner wall surface of a heating chamber 3 that is easily contaminated can be cleaned while being visually checked. The heating container 2b and the open/close door 2a are separately produced, and can be individually stored, conveyed and stacked, thereby reducing a rejection rate due to deformation and increasing productivity in an assembling process.Type: GrantFiled: September 16, 2009Date of Patent: January 24, 2012Assignee: Sharp Kabushiki KaishaInventor: Masayuki Uno

Patent number: 8080765Abstract: A substrate heating apparatus includes a top plate arranged above a hot plate so that a vertical space is formed between the hot plate and the top plate. The top plate has an evacuated internal chamber serving as a vacuum insulating layer that suppresses heat transfer from a first surface of the top plate facing the hot plate to a second surface of the top plate opposite to the first surface. When heating the substrate, a gas flow flowing through the space between the hot plate and the top plate is generated.Type: GrantFiled: September 13, 2010Date of Patent: December 20, 2011Assignee: Tokyo Electron LimitedInventors: Shinichi Hayashi, Tetsuo Fukuoka, Tetsuya Oda, Hiroaki Inadomi
